TVS - Varistors, MOVs (Transient Voltage Suppressors, Metal Oxide Varistors) are devices that help protect sensitive electronic circuitry from damage caused by voltage transients. The VM155MK122R030P050 is one such device that is designed to protect valuable, sensitive electronic equipment against over- or under-voltage spikes that occur in various types of situations.

The VM155MK122R030P050 is part of the series of low-cost, high-security metal oxide varistors (MOVs) from EPCOS. This device is designed for a wide range of consumer applications, such as PC and laptop motherboards, printed circuit boards, and other consumer electronic equipment. It’s also designed for use in automotive-sector applications as well.

The VM155MK122R030P050 features a maximum voltage rating of 55V with a breakdown voltage of 29V. This is a three-terminal device which is composed of a zinc-oxide, non-linear resistor surrounded by a silicon-rubber outer casing. With its mounting holes and low profile, it’s easy to install and requires minimal space for installation. It also has a dielectric strength rating of 30VAC, making it well-suited for a wide range of applications.

The working principle of the VM155MK122R030P050 is that when a voltage transient occurs, the voltage will rise above the rated voltage rating of 55V. This will cause the zinc-oxide non-linear resistor to decrease its resistance. As a result, the voltage will drop back below the breakdown voltage of 29V, dissipating unwanted energy and protecting the equipment from damage.

The VM155MK122R030P050 is an ideal choice for many applications due to its low cost and high durability. It is designed to be able to handle multiple consecutive over- or under-voltage spikes, and is well suited for a wide range of consumer and automotive applications. It is easy to install, lightweight, and requires minimal space for installation, making it the perfect choice for companies looking for a reliable, cost-effective solution to protect their valuable electronic equipment.
